Why Do Teeth Wear Down?

Our smile is the best business card we present to the world. Over time, however, we may face problems such as yellowing, shortening or sensitivity in our teeth. One of the biggest hidden dangers behind these problems is tooth wear. So why do teeth wear down, and what can be done to prevent it?

In this article, we look at the factors that damage tooth structure, the types of wear and the solutions offered by modern dentistry.

What Is Tooth Wear?

Tooth wear is the gradual loss of tooth enamel, the outermost protective layer of the tooth, and the dentin beneath it. It rarely has a single cause; mechanical stress, chemical effects or age can all trigger it.

Why Do Teeth Wear Down? The 4 Most Common Causes

In dentistry, tooth wear is classified into 4 main types according to how it develops. Understanding why your teeth are wearing down is the first step towards the right treatment:

1. Clenching and Grinding (Bruxism / Attrition)

Stress, one of the biggest problems of modern life, can show itself at night as teeth clenching.

• Result: As the upper and lower teeth rub against each other, the teeth become shorter, chewing surfaces flatten and cracks form.

2. Acidic Foods and Reflux (Erosion)

This is wear caused entirely by chemical (acid) action, without any mechanical friction.

• Result: Excessive consumption of citrus fruits, fizzy and acidic drinks, stomach conditions (reflux) or vomiting (bulimia) bring acid into the mouth and dissolve tooth enamel.

3. Incorrect Brushing and Hard Toothbrushes (Abrasion)

While trying to clean your teeth, you may actually be damaging them.

• Result: Using hard-bristled brushes, brushing too hard in a horizontal direction or constantly using highly abrasive whitening toothpastes wears away enamel. It usually appears as notches where the tooth meets the gum.

4. Faulty Bite and Functional Disorders (Abfraction)

Due to problems with the jaw structure or missing teeth, some teeth carry much more load than normal.

• Result: Micro-cracks and tissue loss occur at the neck of the tooth (close to the gum line).

What Are the Signs of Tooth Wear?

You may notice that your teeth have started to wear from the following signs:

• Hot and Cold Sensitivity: When the protective enamel layer becomes thinner, the nerve channels beneath it are exposed.

• Discoloration: As the enamel dissolves, the more yellow dentin layer underneath becomes visible.

• Changes in Tooth Shape: The edges of the teeth become translucent, jagged or develop micro-fractures.

• Jaw Pain and Headaches: Especially with wear caused by bruxism, there is pain and fatigue in the jaw joint in the mornings.

How Is Tooth Wear Treated?

Unfortunately, worn tooth enamel cannot regenerate itself. That is why early intervention is so important. Popular treatments used by dentists include:

Golden Tips for Preventing Tooth Wear

• Choose a soft or medium toothbrush and brush using circular motions.

• Do not brush immediately after eating acidic foods. Rinse your mouth with water and wait at least 30 minutes before brushing.

• If you have reflux or stomach problems, be sure to see a gastroenterologist.

• Manage your stress, and if you notice that you clench your teeth, see a dentist to discuss options such as a night guard or masseter Botox.

To protect the health of your smile and prevent tooth wear, don't forget to have regular dental check-ups at least twice a year.
